SIDE FRAME FOR CARTRUCKS.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed Iuly'30, 1914. Serial No. 854,056.

T0 all whom it may concern:

Be it known that LEDWIN H. BENNEns, a citizen of the United States,residing at Elizabeth, county of Union, and State of New Jersey, haveinvented a certain new and useful Side Frame for Car-Trucks, of whichthe following is a specification.

This invention is an open piece side frame for car trucks, the samebeing more particularly intended as an improvement upon the structureforming the subject matter of`my prior Patent No. 872,790, grantedDecember 3,1907.

The object of the invention is to stiften the frame by a distribution ofthe metal with a view to taking care of the stresses which tend tobuckle or distort the structure without, however, increasing to anysubstantial extent the weight of the frame.

A further object is to produce a frame the length of which exceeds thelinear dimensions of an ordinary frame, which longer frame involves aconstruction reinforced at certain places so as to withstand thestresses and at the same time is not disproportionately increased inweight.

The invention embodies a cast side frame comprising upper and lowerchords and upright struts connecting said chords and forming with thesame a central bolster opening and a plurality of other openingspositioned at the respective sides ofsaid central opening, said chordsand struts being channel-shaped in cross section, with the channelsfacing inwardly and bounding the openin s other than the bolsteropening, and with the marginal portions of said channels provided withrentrant flanges.

The invention embodies, also, a lower chord or member of box-like crosssection, said lower member or chord being provided at the top thereofwith inwardly projecting or rentrant flanges overhanging the top of thechamber in said box.

The invention comprises, also, an elongated cast metal frame embodyingtop and bottom chords and vertical Webs connecting said chords, saidwebs being provided in addition tothe central bolster opening with aplurality of openings at each side of the bolster opening, a salientfeature of the elongated frame being the employment` of columns betweenthe openings and intermediate the Webs, which columns and webs arechannel-shaped in cross section to afford or chord B is considerably therequired strength to resist the stresses that tend to buckle or distortthe frame.

Other features and advantages of the invention will appear from thefollowing detail description.

In the drawings, Figure 1 is a side elevation partly in vertical sectionof a castl metal side frame embodying the invention. Fig. 2 is a planview thereof. Fig. 3 is a vertical cross section in the plane of thedotted line 3-3 of Fig. 1 looking in the direction of the arrow. Fig. 4is a horizontal sectional plan view, the plane of the section beingindicated by the dotted line 4--4 of Fig. 1.` Fig. 5 is a transversevertical section on the line 5-5 of Fig. 1. Fig. 6 is a side elevationpartly in vertical section of a long side frame, wherein a plurality ofopenings are provided at each side of the central bolster opening andver/tical Ycolumns are employed intermediate 4the side openings. Fig. 7is a vertical cross section on the line 7-7 of Fig. 6. Fig. 8 is ahorizontal section on the line 8-8 of Fig. 6. Fig. 9 is a vertical crosssection on the line 9-9 of Fig. 6.

The Side frame illustrated in Figs., 1 a)v 5, inclusive, embodies a topmember A, a bottom member B, and side members C D, the latter being inthe form of plates or webs connecting the top member and the bottommember. The top member and the bottom member A B constitute the top andbottom chords respectively of the frame, all the parts of which areintegral, being cast in one piece. As shown, the top member A is curvedin the direction of its length, the respective end portions a of saidtop member being inclined. For the purpose of reducing the weight, thetop member is provided with openings a separated by intervening bridgebars a2. The top member and the bottom member are joined with the websor .plates channel-shaped in cross section, said channels facinginwardly. The bottom member shorter than the top member A, and at therespective ends of the frame there are provided walls or members E, thelatter being inclined upwardly from the bottom member and-extended toform seats c which join with the inclined extremities a, so as toconstitute a firm bearing for an axle box. The side members C D areprovided with central openingsv sob adapted to receive the usualbolster, the marginal edges ofsaid bolster openings F being formed bycolumns f adapted to be slidably engaged with the bolster and to performthe function of guides therefor. In addition to the bolster opening Fthe side members C D of the frame are rovided with openings G G, thelatter being positioned on opposite sides of the bolster opening. Theprovision of these side openlngs G G', reduces the weight of the metalin the side frame, `but to take care of the stresses said openings areprovided at the lower portion with a curved webdq integral with therespective side plates an connecting the latter at the lower-portion ofsaid openings -G G. The side webs yC D and the inclined end members Eare joined to constitute a member channel-shaped in cross section, asillustrated in Fig. 5, and to further increase the rigidity andstiffness of the frame so as to preclude buckling or distortion underthe stresses, I provide the rentrant ianges g', the latter extendingfrom the respective end portions of the web g so as to conistituteboundaries for the lmarginal edges of the openings G G. These rentrantfianges q extend inwardly from the res ective side webs, as shown inFig. 5, an if desired said rentrant flan es may extend entirely aroundthe margini! edgesof the openin but it is preferred to cut out some of te metal on the sides of the openings next to the column guides', seeFig.`1. f

A The bottom member or chord B is boxshape or channeled in crosssection, and said bottom memberconsists of a lower web b, a plurality ofupstanding webs b', upwardly extending top flanges b2, and inwardlyextending or rentrant -ianges b3 see Fig. 3. The channel or box .shapevothe bottom member reduces the weight of themmetal in the lower part of'theA frame, whereas the webs and lflanges composing `said member impartthe required rigidity and stiffness to the bottom chord. The flanges b2b3 are provided with perforations adapted to receive bolts by whichcertain angles may be fastened to the bottom memer, certain of saidopenings serving as drain holes for the escape of water from theinterior of the bottom member. The rigidity of the bottom member isincreased b v the addition of. the rentran-t flanges b, the latterconstituting distinctly tures in the construction of the skeletonizedbottom chord.

The upwardly inclined members E' are shown as having Ilugs k extendingoutwardly therefrom intermediate the end portions of said members,and tothese lugs are attached stays H adapted to be fastened to an axle box(not shown). It is apparent that when required suitable interposedliners may be used in connection with the stays novel feafor linin upthe axle boxes asv required, but as sui liners constitute no part ofthis invention, I have not considered it necessary to illustrate thesame herein.

I designate brake beam hangers fastened to one of the side webscomposing the frame, said hangers being positioned at the respectivesides of the bolster opening and extending outwardly -from the frame.

The construction illustrated in Figs. 6 to 9,'inclusive, of the drawingsembodies the salientfeatures ,of the' invention as here` toforedescribed, but the frame therein illustrated is intended to beconsiderably longer than the frame shown in Fig. l.. It is apparent thatthe frame of Fig. 6 embodies the top member A, thebottom member B, theside webs C D, the inclined members E, the bolster opening F, and theside openings G G, all as hereinbefore disclosed. In addition to theside openings G G the frame is provided with other side openings J J andcolumns K, K', the latter being positioned intermediate the openings G Jand G J and between the side webs C D. The openings described materiallyreduce thel weight of the frame, whereas the columns K K add materiallyto the stiffness of the frame for resisting the stresses. The columns KK are positioned vertically so as to join the top member A and theinclined end members' E, and said columns K also join with therespective side members C D. The frame of Fig. 6 is provided with boxstays H and with the brake beam hangers I, the positions of the latterbeing indicated by dotted lines in Fig. 6, and the same being shown inapplied positions in Fig. 7. It will be noted that the brake beamhangers are applied or attached to one of the side members o posite toor in line with the intermediate co umns K K. That is to say, saidcolumns K K act as vertical struts between the top and bottom chordsand, further, said struts or columns carry the brake beam hangers.Attention is invited to the fact that the top member A is joined withthe side webs C D, which webs are provided with rentrant flanges c,constituting a channel in cross`section with reentrant Hange-s, therebyadding materially to the rigidityand stiffness of the top member withouta proportionate increase in the wei ht of the` metal.
